Abstract : The information presented in this report is based on several years of investigation encompassing studies, research and development of bio-instrumentation, and consultation with researchers in the field of animal tracking and remote bio-data acquisition. A summary of the work is presented along with descriptions of the instrumentation devices and concepts which resulted. This instrumentation includes a portable radio telemetry system consisting of a base station receiver, directional antenna, digital data display, bird and aquatic animal beacons, and telemetry devices and data sensors. An evaluation of past activities and results is made with the benefit of some hindsight and with a view to providing guidelines for future planning and recommendations for a practical program of instrumentation studies of the future.
